Associated factors of modern contraceptive use among women infected with human immunodeficiency virus in Enemay District, Northwest Ethiopia: a facility-based cross-sectional study.

BACKGROUND: The prevention of unplanned pregnancy among women infected with human immunodeficiency virus (HIV) is critical for the prevention of mother-to-child transmission (PMTCT) of HIV. Of the prevention strategies, deployment of modern contraceptives is principal one. However, there were limited facts on utilization of modern contraceptives and associated factors among HIV infected women, in particular of resource-limited settings in Ethiopia. Hence, we aimed to quantify the proportion of modern contraceptive utilization and the possible related factors among women infected HIV.
METHODS: A facility-based cross-sectional study was conducted on randomly selected 632 women infected with HIV from 05 February to 25 March 2018. Data on their treatment, socio-economic, and demographic background were collected through a structured interviewer administered questionnaire. Binary logistic regression model was fitted to identify the associated factors of modern contraceptive use among women infected with HIV. RESULT: We found 61.4% (95% CI, 57.6-65.2) were using modern contraceptives. Greater than four family size (AOR:2.17; 95%CI: 1.31-3.59), family planning counseling service (AOR: 2.37; 95% CI: 1.44-3.91), discussing contraceptive issues with sexual partner (AOR: 1.76; 95% CI: 1.12-2.77), history of giving birth (s) (AOR:2.21; 95%CI:1.20-4.05) and World Health Organization (WHO) clinical stage III or IV (AOR: 3.59; 95%CI: 1.37, 9.44) were positively associated with modern contraceptives use, whereas, older age (AOR: 0.45; 95% CI: 0.24-0.81) and being widowed (AOR: 0.34; 95% CI: 0.14-0.83), abridged the chances of modern contraceptives use.
CONCLUSION: The prevalence of modern contraceptive use among women infected with HIV is low. Higher family size, counseling on contraceptives, discussing contraceptives issues with partner, history of giving births and WHO clinical stage III/IV were positively related with contraceptives use, whereas, older age and being widowed abridged the chances of contraceptives use among HIV infected women. Therefore, our findings support calls for the district health office and the antiretroviral treatment clinics of the resource-limited settings to work more on family planning counseling services and promoting more dialogues with sexual partners on modern contraceptives use.

Background

Globally, an estimated 18.2 million women were infected with human immunodeficiency virus (HIV) in 2017 [1], and about 1.3 million women infected with HIV come to be pregnant every year [2]. World Health Organization (WHO) reported that an estimated 1.8 million children were living with HIV globally in 2017, whereas 180,000 children were newly infected with HIV [1]. Most of these children were living in sub-Saharan Africa and they were infected with HIV through mother-to-child transmission (MTCT) [3]. MTCT of HIV occurs when HIV is transmitted from a woman infected with HIV to her baby during pregnancy, labor or delivery, or through breastfeeding after giving of birth [4]. MTCT of HIV is a significant contributor to the burden of HIV, accounts for 9% of new infections globally [4]. HIV infection of infants results in early mortality or creates a lifelong chronic condition that greatly shortens life expectancy [4].

Many reproductive age women are simultaneously at risk for both HIV infection and unwanted pregnancy. This is more sever in sub-Saharan Africa, where the rate of unintended pregnancy among HIV infected women range from 51 to 84% [5, 6].

Hence, prevention of unintended pregnancies among HIV infected women is one of the main intervention strategies to prevent MTCT of HIV [7, 8]. Studies suggested that the effect of preventing unintended pregnancies among HIV infected women can be proportional or more pronounced than the contribution of antiretroviral treatment (ART) provision for pregnant women to prevent MTCT [9, 10]. Provision of appropriate counseling and contraceptive methods to WLHIV is recommended to ensure protection from unintended pregnancy [8, 11–13].

However, utilization of modern contraceptives among women infected with HIV is subjected with many different factors compared to HIV negative women of reproductive age. Evidences supported that freely open discussion about family planning with spouse and health workers [14-18], disclosure of HIV sero-status and discussion on fertility issue [19], being married, as well as older age of women [20], were substantial related factors of modern contraceptives use among HIV infected women. On the other hand, contradicting findings were also reported from Uganda and Kenya [18, 21] about the link between women’s educational status and modern contraceptives utilization.

Hence, special attentions are needed to reduce MTCT especially in low- and middle-income countries [1, 6, 22–24] by avoiding unintended pregnancies through the utilization of modern contraceptives [25]. Evidences indicated that contraceptive use averts 19.7% of MTCT, and 13.1% of deaths [10]. In the settings where HIV prevalence is high, management of sexual and reproductive health of women infected with HIV is critical to reduce HIV transmission and maternal mortality. In Ethiopia, an estimated 1.2% of all women and 1.5% of reproductive age women are living with HIV [26].

However, there is paucity of data on modern contraceptives use and its associated factors among HIV infected women in the childbearing age. Hence, this study aimed to determine the level of modern contraceptive use and its predictors among HIV infected women in the childbearing age.

Methods

Study design and setting

A facility-based cross-sectional study was conducted from 05 February to 25 March 2018 in Enemay District, Northwest Ethiopia. Enemay district is located 91 Kms due North from Debre Markos, the main town of East Gojjam Zone, and 245 km due East from Bahir Dar, the main town of Amhara national regional state. In 2018, the catchment population of the district was estimated to be about 200,000. The district had three ART centers (Bichena primary hospital, Yetmen health center and Bichena health center), 1878 reproductive age women infected with HIV were enrolled in the ART centers for HIV care services. The average daily patient visit of the ART centers was estimated to be 40 HIV infected women per day.

Study population and eligibility

HIV infected women in the childbearing age who were receiving HIV care services from all the three ART centers of Enemay District were the study population. HIV infected women in the childbearing age who were at risk of pregnancy [i.e. women who were fecund, sexually active, and non-pregnant] were eligible for this study, whereas, pregnant women and sexually active HIV infected women in the childbearing age who were incapable to conceive for different reasons (for example, hysterectomy) were excluded from this study.

Sample size determination and sampling procedure

The sample size of this study was determined using single population proportion formula:

with the assumptions of 53.7% contraceptive users (p) among HIV positive women [17], 95% confidence level, and a maximum of 5% marginal error (d). Taking a non-response rate of 10% and 1.5 design effect, the final sample size was 632.

The total sample size was allocated proportionally to the three ART centers in the District based on the number of HIV positive women in reproductive age who were on HIV care. Then, the study participants were selected through systematic random sampling of every other HIV infected women from the three study sites. The first HIV infected women coming to each ART center on the random start date was considered as a starting point of interviewing, and then we interviewed every other HIV infected women in the order of their visit until the calculated sample size in the respective ART center was saturated (Fig. 1).

Data collection tools and procedures

Data were collected through interviewer-administered structured questionnaires, which were first prepared in English, then translated to the local language, Amharic, by language and public health experts. The data collection tool was pre-tested on 5% of the total sample (30HIV infected childbearing age women) out of the study area to ensure internal validity of the study. Then all the necessary corrections were also amended before the actual data collection based on the pre-test information we found. Three diploma nurses and two BSc nurses were employed as data collectors and supervisors respectively after training on the techniques of interviewing, handling ethical issues, maintaining confidentiality and privacy was provided by the principal investigator.

Study variables and measurements

The dependent variable of this study was modern contraceptives use that was assessed through self-reported contraceptives use to delay or avoid pregnancy at the time of the study from a recognized family planning service provider facility. Modern contraceptive use was defined as the use of any method of modern contraceptive such as oral contraceptives/pills, injectable, Implants, intrauterine device (IUD), male or female condoms (restricted to those reporting “always” use or use frequently in all vaginal sexual relationships), and permanent methods such as vasectomy and Tubaligation [27, 28].

Independent variables included for this study were demographic and socio-economic characteristics (age, residence, religion, educational status, marital status, occupation, household’s monthly income, family size), reproductive health related characteristics (history of abortion, ever heard about modern contraceptives, type of modern contraceptives ever heard about, source of information, reasons to use modern contraceptive, reasons not to use modern contraceptive), and HIV care related characteristics (husband/partner sero status, disclosure of HIV, duration on ART, WHO clinical stage).

Data management and statistical analysis

Data were checked for consistency, entered into Epi Info™ version 7.2, and then exported to SPSS version 25 for statistical analysis. Descriptive measures were computed to summarize the study participants and modern contraceptive utilization by background characteristics. Binary logistic regression model was fitted to identify factors associated with modern contraceptive use among HIV infected women. In the bi-variable analysis, independent variables with p-value less than 0.25 were included in multivariable logistic regression analysis to control possible confounders [29]. Model fitness was assessed with Hosmer and Lemeshow goodness of fit test, and Hosmer Lemeshow test greater or equal to 0.05 was considered to ensure goodness of fit of the model. Adjusted odd ratio (AOR) with 95% confidence level (CI) were used to declare statistically significant association between the outcome variable and independent variables.

Ethical considerations

Ethical clearance and approval was obtained from the ethical review committee of Debre Markos University. Prior to interviewing, informed verbal consent was obtained from each participant after explaining the purpose and importance of the study. In case of minors (participants below 18 years old), verbal assent was obtained from the minors themselves and their parents or guardians. Participation was on a voluntary basis and the data were kept anonymous.

Results

Socio-demographic characteristics of the study participants

A total of 632 reproductive age women infected with HIV were involved in this study. The mean ± with its corresponding standard deviation of age of them was 31.1 ± 6.9 years and nearly half (45%) of the respondents were in the age group of 25 to 34 years. The samples were predominantly urban (60%) and orthodox Christian religion followers (74%). With regard to their occupation, 51% were farmers/Housewife. The result of this study also showed that 59% were married and 43% were cannot read and write of the total study participants (Table 1).

Proportion of modern contraceptive use among HIV infected women

The result of this study showed that 388 (61.4% [95%CI: 57.6, 65.2]) participants were using modern contraceptive method, of which nearly 32% of contraceptive users were in the age group of 25–34 years. Nearly two-fifth (39%) of HIV infected women were married and urban residents (Table 2).

Among HIV infected women who were using modern contraceptives, 49% of them had history of giving birth; of which, 7% had also experienced abortion. More than one-third of the participants (36%) discussed with their partner/husband about modern contraceptives, whereas almost all of the participants had ever heard about modern contraceptives (Table 3).

The average length of time that women had been receiving care at the clinics was 4.6 years (±2.4SD). Forty three percent of modern contraceptive users had disclosed their sero-positivity status for HIV to close family members or communities, parents (37%) and 23% to partners/ husbands). Among the total of samples who were using modern contraceptives, 57% of them were in WHO clinical stage I/II (Table 4).

Factors associated with modern contraceptive use among HIV infected women

Table 5 summarizes the findings of our bivariate and multiple variable binary logistic regression analyses on the factors that associated with modern contraceptives use among HIV infected women. The middle age group were less likely to use modern contraceptives, women aged 35–49 years decreases the odds by 55% to use modern contraceptives compared with whose age was between 15 to 24 years (AOR = 0.45; 95% CI: 0.24–0.81).

Marital status and parity as part of socio-demographic standard variables were also significantly affected the use of modern contraceptive use: Being widowed decreases the odds by 66% to use modern contraceptive as compared with singles (AOR: 0.34; 95% CI: 0.14–0.83), whereas, those who gave birth had the odds of 2.21 to use modern contraceptives than who don’t gave birth (AOR = 2.21; 95% CI: 1.20–4.05) Number of birth history had also significant relationship with modern contraceptives use; those women whose family size is four or more had the odds of 2.17 to use contraceptives than their counterparts (AOR = 2.17; 95%CI: 1.31–3.59).

Moreover, from the reproductive health related characteristics and counseling services, discussion with their partner were persistent predictors of modern contraceptives use. Holding the other variables constant, those women who got modern contraceptives had the odds of 2.37 to use modern contraceptives use than who don’t get counseling services (AOR = 2.37; 95% CI: 1.44–3.91). Whereas, women who had discussed with their partner about modern contraceptives had the odds of 1.76 to use modern contraceptives than their counterparts (AOR = 1.76; 95% CI: 1.12–2.77). Turning towards to their clinical characteristics we found WHO clinical stages were significant factors for modern contraceptives use; those women who developed WHO III/IV clinical Stages had the odds of 3.59 to use modern contraceptives than WHO I/II clinical Stages (AOR: 3.59; 95%CI: 1.37, 9.44) (Table 5).

We examined the data to see if our strongest associations were modified by residency or educational status. We found no evidence that the associations between modern contraceptive use, income, religion, occupation, other reproductive health and clinical characteristics.

Discussion

This study set out to determine the proportion of modern contraceptive use among HIV infected women and to examine the associated factors during the course of their treatment. We found that the proportion of modern contraceptives use was 61.4%. Family size, FP counseling service, open discussion with partner on modern contraceptives issues, history of giving birth (s) and WHO Clinical stage II/IV, were all independently and positively associated with modern contraceptives use. Middle age (35–49 years) and being widowed reduced the odds of modern contraceptive use.

With regard to the proportion of modern contraceptives use, comparable findings were also reported from Southwest Ethiopia, 64% [15], and Western parts of Ethiopia at Gimbie town, 57% [30], and From Southern parts of Ethiopia at Yirgalem Hospital ART Centre, 62% [31].. However, higher than the current finding from Northwest parts of Ethiopia at Bahir Dar, 80% [32], and from Western Ethiopia at Nekemte town, 66.4% [33] and lower findings from Oromia region, Ethiopia, (46%) [34], Northern Ethiopia, 50% [35], 44% [36] and 46.3% [17], Northwest Ethiopia (48%) [37], Ghana, 43% [38], Nigeria,10% [39] and Kenya, 34% [40] was also reported. This variation among reports might be due to differences in background characteristics of the respondents, health service availability and accessibility, community awareness on modern contraceptives, presence of partners working on maternal health particularly on family planning services and health professionals’ health service provision experience.

The finding of this study was also higher than the study found on the general population of Ethiopia, 35% [41]. This can be possibly explained by that special attention for women on HIV care in terms of modern contraceptives service provision including contraceptive method supply, counseling services and others health care follow-ups. This may enhance modern contraceptives utilization among HIV infected women compared with the general population..

Despite, modern contraceptive methods were freely available in health facilities including at the ART clinics, nearly two-fifth of HIV infected women do not used any of the modern contraceptives methods. However, the Ethiopian HIV/AIDS prevention and control program national guidelines advocate for dual family planning methods to prevent HIV/STI transmission and unintended pregnancies for HIV infected individuals, the current study reported that only 4% of women used male condom as dual method of contraception. Parallel finding was also reported from previous survey conducted in the Ethiopian general population [41]. However a bit higher findings was also reported from Northern Ethiopia (59.9%) [17], from Northwest Ethiopia (8%) [35] and Southwest parts of Ethiopia (31.4%) [15].

In the current study, the finding revealed that women infected with HIV had different reasons not to use modern contraceptives. They explained that, the need of giving birth, fear of side effects, religious prohibition and partner opposition were the main reasons not to use modern contraceptives method. This finding was supported with a study done at the Northwest parts of Ethiopia in University of Gondar specialized teaching hospital [35].

Regarding the associated factors, many of the findings are unsurprising and in line with those recent studies related with the current study. For example, the issue of less modern contraceptives utilization among the middle age groups of HIV infected women was also reported from the northwest parts of Ethiopia at University of Gondar specialized Hospital [35], from the southwest parts of Ethiopia at Mizan-Tepi Teaching and Referral Hospital [15] and from the northern parts of Ethiopia at Tigray zonal hospitals [17]. This is possibly explained by that women under this age group may expect that there may be physiological cessation of menses and fear of the side effects while age increases. It can also be possibly justified by that misconception, cultural and religious barriers may affect the attitude of HIV infected women towards modern contraceptive utilization [42]. Similarly, widowed marital status was negatively associated with modern contraceptive utilization, which is also consistent with a recent study finding from the Southwest Ethiopia at Mizan-Tepi Teaching and Referral Hospital [15]. This is because of that the probability of doing sexual intercourse among widowed HIV infected women is negligible, which also indirectly increases the probability of not using modern contraceptives among them.

On the other hand, having a family size of four or more was statistically significant in relation to modern contraceptives use among women on HIV care, which was in line with a finding in Gimbie town, West Ethiopia [30]. This can be further explored that women who have higher number of family size might have lesser desire to have children than those who had four or less family size.

The strong association we found between discussion of contraceptive issues with their partner/husband and modern contraceptives use was also already established from northern Ethiopia [14, 17], Addis Ababa, Ethiopia [16] and Southwest Ethiopia [15], which might be because of these women’s freedom to negotiate their partners in decisions of birth limiting or spacing and safe sexual practice.

Moreover, getting family planning counseling services had increased odds of contraceptives utilization, which could also be explained by the assumption that women could get advice on the importance of modern contraceptives use, how to negotiate with sexual partner and risk reduction strategies.

Once more, this study showed that women who were at advanced stage of the disease had also increased odds of modern contraceptives utilization compared with their counterparts, which can also be explained by that due to fear of pregnancy related complications and the occurrence of opportunistic infection as clinical stage increases.

This study acknowledged some limitations. First, the study design makes it difficult to establish causality. This is because the cross sectional nature of this study in which cause-effect relationship couldn’t be established [43, 44]. Second, though there are wide ranges of factors, which affect utilization of contraceptive methods among HIV positive women, only individual level factors were addressed in this study. Hence, this is the interest of the authors to warrant further investigation to explore about the relationship between service providers related factors, structural barriers and modern contraceptive use among HIV infected women.

Conclusion

Modern contraceptive use among women infected with HIV is better than the general population in Ethiopia. Higher family size, counseling on contraceptives, discussing contraceptive issues with partner, history of giving births and WHO clinical stage III/IV were positively associated with contraceptive use, whereas, older age and being widowed reduced the odds of contraceptive use among HIV infected women. Therefore, our findings support calls for the district health office and the antiretroviral treatment clinics of the resource-limited settings to work more on family planning counseling services and promoting discussions with sexual partners on modern contraceptives use.
